Tuning and toggling Turing patterns in gene circuits
Abstract
Controlling spatial patterns in synthetic biological systems remains challenging due to limited robustness and tunability. Here, we report two complementary mechanisms—the pattern switch and the pattern dial—for systematic control of Turing pattern formation in gene circuits. The pattern switch toggles the onset of patterning through a single parameter, while the pattern dial enables smooth transitions between distinct pattern types using weakly nonlinear analysis. We show that small genetic networks are easier to control but less robust, whereas larger networks gain robustness at the cost of tunability, revealing a trade-off between evolvability and designability. Our framework offers experimentally testable design rules for engineering programmable spatial patterns in living systems.
